ladle shroud

junhuamachinery

The ladle shroud nozzle forcontinuous casting is also called the protective sleeve. It is an importantcomponent connecting the ladle and the tundish. It is connected to the lowershroud of the sliding shroud device at the bottom of the ladle, and the lowerend extends into the tundish.

The shroud is an important functional refractorymaterial for maintaining casting and improving steel quality. The length ofthe shroud is generally 600-1800mm, the pipe diameter is 90-150 mm, and thestructure of the ladle shroud nozzle is shown in Figure 2. Its use conditionsare harsh and must have the following functions: excellent thermal shockresistance; good mechanical strength; excellent resistance to alternatingcorrosion of molten steel and slag, high oxidation resistance, and in addition,other suitable properties are required for some special steel grades.moreinformation,please check here

Slide Gate Plate is a criticalcomponent in the continuous casting process, used to control the flow of moltensteel from the ladle or tundish to the crystallizer. The following is adetailed description:

Role and Function

·       Flow Control: The sliding gate plate adjusts theopening size of the nozzle through the sliding mechanism, thereby controllingthe flow of molten steel. This is very important for maintaining a constant andcontrollable casting process.

·       Operational Flexibility: Thesliding gate plate allows operators to adjust the molten steel flow rate asneeded during the casting process to adapt to different production requirementsand conditions.

·       Emergency Stop: In anemergency, the sliding gate plate can completelyclose the flow channel and stop the flow of molten steel, thereby preventingaccidents and losses.

Slide gate plate for Converter
The slide gate plate is madeof sintered corundum, fused corundum, fused zirconium corundum, zirconiummullite and other main raw materials. It is combined with new resin, formed byhigh pressure and fired at high temperature. It has the advantages of highstrength, super hard, high temperature resistance and corrosion resistance, andstrong thermal stability.

Stopper

  

MonoblockStopper is used mainly for flow control on Molten Steel poured fromtundish to mould. Monolithic Stopper is installed in the Tundish above the Sub Entry Nozzle and the gap between stopper head and Nozzle decide thethroughput requirement of Molten Steel inside the Mould.

Argon can be blown into the tundishthrough argon inlet to prevent nozzle from Clogging ( specially designedfeature wherever it is required we design and customise accordingly)

SPECIAL FEATURES:
o Facility for gas purging
o Anti oxidant properties
o Design and size as per customer’s requirement
o Clogging free casting for long sequence of casting
o Gas purging facilities to prevent alumina clogging (optional)
o Slag zone immersed part re-inforcement with special material for long life
o Argon sealing purging arrangement can be provided on customer’s request
o Wide range of formulation for withstanding oxidation and long sequencecasting
o Different assembly methods for assured security even in long sequence casting
o We manufacture Silica free Oxy-bore ladle shroud for less corrosion and longsequence casting
